1a.Objectives (from AD-416)
An objective of the Delta Obesity Prevention Research Unit (Delta OPRU) being conducted in part under this cooperative agreement is to identify barriers and facilitators to adherence to the Dietary Guidelines for Americans (DG) and examine how differential profiles of adherence relate to obesity in children and adults of the Delta region. The specific objective of this cooperative agreement is to establish and support a cooperative partnership between the United States Department of Agriculture (USDA), Agricultural Research Service (ARS) and Tufts University (Tufts) which will permit scientific work amongst ARS/Tufts Nutrition Scientists to construct conceptually and culturally appropriate survey tools to assess DG adherence barriers and facilitators for African-American and Caucasian children and their caregivers of the Lower Mississippi Delta (LMD) region and elsewhere in the U.S.
1b.Approach (from AD-416)
The Delta Obesity Prevention Research Unit (Delta OPRU), in partnership with Tufts University and other research cooperators, will use data obtained from nominal group methodology, to construct conceptually and culturally appropriate survey tools to assess the adherence to the USDA Dietary Guidelines of African American and Caucasian fifth grade children and their caregivers in the Lower Mississippi Delta region and elsewhere in the U.S. Tufts scientists will contribute expertise in dietary intake assessment, sampling design, and data entry management for this survey the HEALTH study. Tufts scientists will also provide technical expertise in pilot research using dietary data, for the identification of dietary patterns which will be adapted to the DG for the LMD and other participating sites. These data will be used to determine the feasibility of the adoption of these patterns in the prevention of obesity. Tufts’ representative will provide technical expertise in proposal writing, data analysis and manuscript preparation.
The cognitive interviews for children have been completed. Recruiting for the adult cognitive interviews has been started. Interviews are expected to be completed this year with the NGT group sessions taking place during the Fall of the 2009 and Spring of 2010 school year.
The majority of the children interviewed had difficulty interpreting some of the prepared questions about the various food groups of MyPyramid. Most did not know what the word recommendation means. Physical activity, saturated fats and added sugars, and grains groups all had words or concepts that were difficult for the kids to understand.
All 12 cognitive interviews have been completed for children. Recruitment for the 12 adult cognitive interviews are in progress. Recruitment is much more difficult for adults than it was for children. Alternative recruitment options are in place. Completion is expected this year with the NGT group sessions taking place during the Fall of the 2009 and Spring of 2010 school year. Translation of the NGT materials (handouts, preambles, etc.) is completed and awaiting back translation.
Monitoring of cooperator's performance and adherence to conditions of the agreement was accomplished by monthly conference calls and an annual report containing information on progress towards goals and objectives.
